IMPROVED MEAT-MINCING MACHINE.

Specification forming part of Letters Patent No. 36,229, dated August 19, 1862.

To all whom it may concern.-

Be it known that I, PURoHEs MILEs, of the city and county of New Haven, and State of Connecticut, have invented new and useful Improvements in Mincing-Machines; and I do hereby declare that the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompany drawings making a part of this specification, in which Figure 1 is a perspective view of amachine complete and working. Fig. 2 is a longitudinal section. Fig. 3 is a transverse section, 1 2. Figs. 4 and 5 are sections of one set of cutters enlarged. Fig. 6 is a perspective View of the box. Fig. 7 is a side view of the clamp used to fasten the box to a table.

. Same letters refer to like parts.

The nature of my invention consists, first, in the peculiar construction of the cutters, whereby I attain cheapness of construction and. increased facility for cleaning after use, as when the machine is open they may be readily removed, cleaned, and reset into the 'machine for use without extra adjustment,

and when the machine is closed for use they are perfectly firm and may be worked with only one set of cutters, or both, as it may be desired to make the mince coarser or finer; secoud,in the construction of the beater-shaft by casting the shaft or arbor,beaters,and forcing-flanges in one piece and forming a groove between each pair of beaters on the shaft for ends of the cutters to rest in for support; third, in the construction and arrangement of a box for a mincer to serve the double purpose of a case to contain the mincer when not in use and to serve as a support for the mincer when in use.

To enable others skilled to make and use my invention, I will proceed to describe its I construction and operation.

Ais the cylinder, opening through the center, hinged at a, and locked together for use.

by the clasp I). In both the upper and lower parts of the cylinder A are formed recesses B to receive the plate 0, containing the cutters D. To make these cutters, or sets of cutters, the steel plates or cutters D are set in the sand before casting, and project into the mold sufficiently that when the metal C is poured in it will flow onto and unite solidly with the plates or cutters D,as shown in Figs. 4 and 5.

E is the arbor,havinga hearing at each end, 0 c, and turned by the crank F.

G are beaters, spirally set and cast on the arbor E, and of one and the same piece.

H H are spiral flanges, also cast on and of;

the same piece of the arbor E. Between the heaters G, on and around the arbor E, are

turned grooves cl, in which rest the end 6 cylinder A, or that portion of it occupied by the spiral flanges H H, and which, in combination with the spiral flanges H H, feed the substance to be minced to the heaters and cutters.

I is the hopper into which the substances to be minced are placed, and from thence pass through the machine out, minced,at the opening 0. On the upper plate of cutters is cast a pin, P, by which to hold the cutters in their place when in the act of closing the machine.

K is a box, apparently ofcommon construction- L is the lid.

m are sockets 0n the side M of the box in which to set the feet a of the machine foruse.

N is a clamp (s, the screw) for holding the box firmly to a table, T. In the side NV of the boxis made a hole, U, through which to clamp it, if desired.

To operate my mincer, place the box K upon a table, as in Fig. 1, set the machine on the side M of the box K, placing the feet at in the sockets in, put the substance. to be minced into the hopper I, turn the crank F,which will revolve the arbor E, and the spiral flanges H H will draw the substance into the cylinder and, revolving, force it around the cylinder and on the spiral ribs f to the spirally set heaters G, which in their turn force it against and past the cutters D, and by continued feeding will carry it through all the cutters and out at the opening 0. If it is desired'to make the mince fine, use both sets of cutters; if coarser, take out one set of cutters and 2 i r V 36,229

The cutters D, united solidly with a metal plate O,by being cast thereon, in combination with the grooves 01, in the manner and for the purpose substantially as set forth.

PURGHES MILES.
